建造北方的威尼斯
Case Study
瑞典首都斯德哥尔摩面对波罗的海，在梅拉伦湖的14个岛屿上建造。市中心旧城区的Gamla Stan是欧洲保存完好的中世纪城市之一。运河上的许多水道和桥是斯德哥尔摩的特征 - 通常称为Beauty on Wateror simplyVenice of the North.
The region is facing major challenges and the need for improved infrastructure is becoming more and more urgent. With approximately 30,000 people moving to the capital every year, equivalent to two buses full of people per day, Stockholm is currently one of the fastest growing metropolitan regions in Europe. The transport system in the capital is vulnerable because there is only one north-south connection running through this city of great cultural and natural heritage.
在地下绕过斯德哥尔摩的交通瓶颈
斯德哥尔摩旁路项目或förbifarten是一个新的21公里的高速公路crossing the Swedish capital, part of the largest infrastructure projects ever made in Sweden. The planning of this 2.7-billion-Euro project commenced in 2006, preliminary construction started in 2014 and the opening is planned for 2026.
已经采取了重大预防措施来保护位于地面上方的景观和周围环境。为了保护斯德哥尔摩的宝贵性质和历史遗址，已决定建造大致建造通过桶18公里的总共21公里nels. Under lake Mälaren the construction will have a depth of65 metres below水体。80％的人将通过拥塞费用和政府资助为20％的费用，但总体公用事业价值被计算出来是从由此产生的经济发展和减少的旅行时间中支付的。估计每天通过145,000辆车，通过城市的旅程将减少到15分钟。
Starting at Kungens Kurva in the south and ending at Häggvik in the north, once the Stockholm Bypass project is finished, it will be the world’s second largest tunnel built in an urban area after the Yamate Tunnel in Tokyo.
在小库尔瓦的建筑物
Long-term customer of Leica Geosystems,Skanska Sverige AB，已赢得了1260万欧元的合同，用于建造隧道的南入口，并将其连接到小动物Kurva的E20高速公路，Scandinavia最大的购物区和瑞典最繁忙的高速公路。这个备受瞩目的项目非常关注安全性，并且不得不减速流量超出必要的速度。
Pontus Holmberg works as chief surveyor for Skanska Sverige at Kungens Kurva. Holmberg is managing field surveyors and the site fleet that mainly consists of drillers, excavators and dozers from different contractors, many of them equipped with machine control solutions from Leica Geosystems. Holmberg works withLeica ConXto transfer model files to the machines and the field crew working on site.
“When working with different contractors on a site like this, it is important that all are working with the latest updated files,”霍姆伯格解释说。“ Leica Conx可以帮助我实时跟踪机器，并实时将文件传输到机器上，以便每个人都在同一页面上。”
在该站点上工作的Epiroc Smartroc T35钻机配备了3D机器控制解决方案，该解决方案是由Leica Geosystems量身定制的Epiroc Smartroc并与Epiroc的HNS传感器系统接口。
钻机遵循数字定义的图案，以钻入岩石的孔以进行爆炸。在工作地点周围的两条高速公路上停止了交通，每天上午10点进行岩石地下的爆炸。或下午2点爆破是在缝合在一起的旧卡车轮胎地毯下进行的，以避免岩石掉入两条道路上。
“如果岩石无意间落在高速公路上，则两个车轮装载机在两侧准备清理道路，以确保道路在尽可能短的一段时间内被阻塞，”Skanska Sverige项目经理Dana Matti解释说。
Staying connected
Nicklas Gustafsson, owner of the companyGranskogens Gräv, is one of the contractors working on site for one and a half years. Gustafsson uses the newLeica MCP80machine control panel on site and he is content with the improvement.“较大的屏幕更容易阅读，并且按钮得到改进，因此这是一个很大的优势，”古斯塔夫森说。
古斯塔夫森（Gustafsson）解释说，这是一个艰难的地下岩石和高地下水位，当在瑞典最繁忙的城市地区建造时，重要的是要拥有可靠的技术解决方案来最大程度地减少停机时间。
“ Leica Geosystems的解决方案可帮助我们与站点办公室保持联系，并确保我们有一个灵活的数据流以支持工作网站上的工作流程.我已经在Liebherr 926紧凑型挖掘机上使用Leica Geosystems的机器控制解决方案工作了四年，” Gustafsson解释说。“我在线上CONXfor most of the day and receive my reference files from Pontus directly on the panel.”
Solutions from Leica Geosystems are key in the multiple stages of constructing interchanges, tunnels and temporary harbours for this big project. Machine control solutions, total stations, prisms and scanners from Leica Geosystems are some of the many products that are needed for a fast and efficient construction of projects at this scale.
